Best Air Insulated Switchgear(AIS) Manufacturer in China ... with the gas insulated switchgear, air-insulated switchgear has more obvious advantages. That's because it does not inflate. It is an easy maintenance inflatable switchgear. The filling gas in the gas insulated switchgear is SF6 and N2 normally, so the maintenance cost is much higher than AIS.[email protected]
